Incentivizing Elimination of Biomass Cooking Fuels with a Reversible Commitment and a Spare LPG Cylinder.

In India, approximately 480,000 deaths occur annually from exposure to household air pollution from the use of biomass cooking fuels. Displacing biomass use with clean fuels, such as liquefied petroleum gas (LPG), can help reduce these deaths. Through government initiatives, most Indian households now own an LPG stove and one LPG cylinder. Many households, however, continue to regularly use indoor biomass-fueled mud stoves (chulhas) alongside LPG. Focusing on this population in rural Maharashtra, India, this study (N = 186) tests the effects of conditioning a sales offer for a spare LPG cylinder on a reversible commitment requiring initially disabling indoor chulhas. We find that almost all relevant households (>98%) were willing to accept this commitment. Indoor chulha use decreased by 90% (95% CI = 80% to 101%) when the sales offer included the commitment, compared to a 23% decrease (95% CI = 14% to 32%) without it. For both treatment groups, we find that 80% purchased the spare cylinder at the end of the study.

Marriage-based pilot clean household fuel intervention in India for improved pregnancy outcomes.

INTRODUCTION: Health interventions often target pregnant women and their unborn children. Interventions in rural India targeting pregnant women, however, often do not cover the critical early windows of susceptibility during the first trimester and parts of the second trimester. This pilot seeks to determine if targeting newlyweds could protect entire pregnancies with a clean stove and fuel intervention. METHODS: We recruited 50 newlywed couples who use biomass as a cooking fuel into a clean cooking intervention that included a liquefied petroleum gas (LPG) stove, two gas cylinders, a table to place the stove on and health education. We first evaluated whether community health workers in this region could identify and recruit couples at marriage. We quantified how many additional days of pregnancy could be covered by an intervention if we recruited at marriage versus recruiting after detection of pregnancy. RESULTS: On average, we identified and visited newlywed couples within 40 (SD 21) days of marriage. Of the 50 couples recruited, 25 pregnancies and 18 deliveries were identified during this 1-year study. Due to challenges securing fuel from the LPG supply system, not all couples received their intervention prior to pregnancy. Regardless, couples recruited in the marriage arm had substantially more days with the intervention than couples recruited into a similar arm recruited at pregnancy (211 SD 46 vs 120 SD 45). At scale, a stove intervention targeting new marriages would cover about twice as many weeks of first pregnancies as an intervention recruiting after detection of pregnancy. CONCLUSIONS: We were able to recruit in early marriage using existing community health workers. Households recruited early in marriage had more days with clean fuel coverage than those recruited at pregnancy. Our findings indicate that recruitment at marriage is feasible and warrants further exploration for stove and other interventions targeting pregnancy-related outcomes.

Feasibility of implementation of simplified management of young infants with possible serious bacterial infection when referral is not feasible in tribal areas of Pune district, Maharashtra, India.

INTRODUCTION: Neonatal infections are a common cause of death in India, but many families cannot access appropriate hospitals for its treatment due to various reasons. We implemented the World Health Organization PSBI management guideline when referral is not feasible within the public health system in Pune, India to evaluate feasibility, barriers and facilitators for its implementation. METHODS: A national-level consultative meeting between government officials and study partners resulted in a consensus on adaptation and implementation in four demonstration sites in selected states in India. At the state and district levels, similar meetings to plan the implementation strategy and roles were held between KEM Hospital Research Centre (KEMHRC) Pune and the public health system Pune, Maharashtra. The public health system was responsible for implementation of the intervention at eight tribal primary health centres (PHC) in Pune district, India, including delivering the intervention and ensuring supplies of all commodities while KEMHRC was responsible for technical support including training of health workers, assistance in PSBI identification and management, data collection and documentation of the implementation strategy. RESULTS: A total of 175 young infants with PSBI were identified and managed. Of these, 34 had critical illness (CI), 46 had clinical severe infection (CSI) and 10 were infants aged 0-6 days with fast breathing (FB) while 85 infants aged 7-59 days had fast breathing. Assuming a 10% incidence of PSBI among all live births, with 3071 live births recorded, the actual incidence of PSBI found in the study was 5.7%, resulting in an actual coverage was of 57%. Among the 90 infants with CI, CSI and FB in 0-6 days, who were advised referral to government tertiary care centre as per the PSBI guideline algorithm, 81 (90%) accepted referral while 9 (10%) refused and were offered treatment at primary health centres (PHC) with a seven-day course of injectable gentamicin and oral amoxicillin. All infants with FB in 7-59 days were offered treatment at PHCs as per the PSBI guideline algorithm with a seven-day course of oral amoxicillin. All except six infants who died and one with FB in 7-59 days, who was lost to follow-up, were successfully cured. Of the six who died, five had CSI and one had CI. Among the 81 infants with CI, CSI and FB in 0-6 days who accepted referral; 48(53%) were successfully referred to government tertiary facility while 33 (36.6%) preferred to visit a private tertiary health facility. The implementation strategy demonstrated a relatively high fidelity, acceptance and intervention penetration. Lack of training and confidence of the public health staff were major challenges faced, which were resolved to a large extent through supportive supervision and re-trainings. CONCLUSION: Management of PSBI is feasible to implement in out-patient facilities in the public health system, but technical support to the health system is required to jump-start the process. Fast breathing in 7-59 days old infants can be managed with oral amoxicillin without referral. A sustainable adoption of this intervention by the health system can lead to decrease in neonatal mortality and morbidity.

Promoting LPG usage during pregnancy: A pilot study in rural Maharashtra, India.

Household air pollution from the combustion of biomass and coal is estimated to cause approximately 780,000 premature deaths a year in India. The government has responded by promoting uptake of liquefied petroleum gas (LPG) by tens of millions of poor rural families. Many poor households with new LPG stoves, however, continue to partially use traditional smoky chulhas. Our primary objective was to evaluate three strategies to transition pregnant women in rural Maharashtra to exclusive use of LPG for cooking. We also measured reductions in kitchen concentrations of PM2.5 before and after our interventions. Our core intervention was a free stove, 2 free LPG cylinders (one on loan until delivery), and repeated health messaging. We measured stove usage of both the traditional and intervention stoves until delivery. In households that received the core intervention, an average of 66% days had no indoor cooking on a chulha. In an adjacent area, we evaluated a conditional cash transfer (CCT) based on usage of LPG in addition to the core intervention. Results were less successful, due to challenges implementing the CCT. Pregnant women in a third nearby area received the core intervention plus a maximum of one 14.2 kg cylinder per month of free fuel. In their homes, 90% of days had no indoor cooking on a chulha. On average, exclusive LPG use decreased kitchen concentrations of PM2.5 by approximately 85% (from 520 to 72 µg/m3). 85% of participating households agreed to pay the deposit on the 2nd cylinder. This high purchase rate suggests they valued how the second cylinder permitted continuous LPG supply. A program to increase access to second cylinders may, thus, be a straightforward way to encourage use of clean fuels in rural areas.

A Low-Cost Stove Use Monitor to Enable Conditional Cash Transfers.

Conditional cash transfers (CCTs)-cash payments provided to households or specific household members who meet defined conditions or fulfill certain behaviors-have been extensively used in India to encourage antenatal care, institutional delivery, and vaccination. This paper describes the social design and technical development of a low-cost, meal-counting stove use monitor (the Pink Key) that enables a CCT based on liquefied petroleum gas (LPG) usage and presents pilot data from its testing and the initial deployment. The system consists of a sensing harness attached to a two-burner LPG stove and an easily removable datalogger. For each cooking event with LPG, households receive 2 rupees-less than the cost of fuel, but enough to partially defray LPG refill costs. The system could enable innovative "self-monitoring" at a large scale-participants initiate the CCT by bringing their Pink Key to antenatal clinic visits, where care providers download data and initiate payments, and participants return the sensor to their stove at home. The system aligns with existing Indian programs to improve health among poor, pregnant women, and contributes a new method to encourage the use of clean cooking technologies.
